Tao and coworkers from Harvard published a study on a “mechanical pill” to directly inject the stomach lining. If this was a sci-fi movie, people would be heading for the exits!

In a nutshell, a pill would be swallowed and the devices would orient to the wall of the stomach or intestine (which would be difficult to control) and then the payload (mRNA) would be injected into the gastrointestinal epithelium and submucosa.

“I can tell you as a doctor, I would be very concerned this could lead to even bigger complications than an injection in the arm,” said Dr. Peter McCullough.
